Mastercraft Boat manufactured boats and often used instrument panels and electrical systems assembled or manufactured by Ace Industries. Typically, Ace would order electrical instruments and other parts and assemble them to specifications that Mastercraft provided. Mastercraft decided to work with a different assembler, M & G Electronics, so it terminated its relationship with Ace. Mastercraft then requested that Ace deliver all of the remaining instruments and other parts that it had purchased for use in Mastercraft boats. Ace delivered the inventory to Mastercraft, which inspected it and kept some of the items, but returned others to Ace, stating that the shipment had been unauthorized. Later, Mastercraft requested that Ace deliver the remaining parts (which Mastercraft had sent back to Ace) to M & G, which Ace did. Mastercraft then refused to pay for these parts, claiming that they were non-conforming. Is Ace entitled to its money for the parts?
